-vf format=nv12,hwupload
that mean I should add -vf format=nv12,hwupload in subprocess.CalledProcess command to use ffmpeg?

11 months ago 这我还真不确定是什么情况，没遇到过……我对ffmpeg其实没有那么熟悉，看起来是在做pitch那个视频的时候出的错。

11 months ago 老师您好，我想请问下我按照您的代码做到最后一步PS D:\five\pitch-visualizer> python gen_pitch.py --audio vocal.mp3 -t F ganbei.MP4 时，它并没有生成一个音频文件，而是出现一下提示：
Generating pitch video
3805frame [01:56, 32.64frame/s]
Combining video
Traceback (most recent call last):

11 months ago 看起来是因为你ffprobe那一步出问题了。你在command line里做ffprobe -v error -select_streams v:0 -show_entries stream=width,height -of csv=s=x:p=0 GANBEI.mp4结果是啥

up主您好，我尝试用您的代码，但发现ffmpeg 报错显示如下：

请问这是ffmpeg 处理视频的问题吗？这该如何解决呢？
